IMO, (I've only had a snake for 4 weeks) but if it's kept indoors near a window, I would personally save money not buying lights for the daytime, so maybe just a pegboard back with some small plastic vents, or have a look online for pictures of cabinets. Good to hear you want to help someone out who needs work and will give it to you at a good price.
Dalbarb makes nice cabinets for retailers, but they have plenty of pics on their site you can get ideas from. Also you could check ebay for pics and ideas.
Sliding doors would give better security against escape at the loss of wide access, or double hinged doors give the access but would need to be securely fastened or locked.
(no links please)
Cheers.
